A 14-year-old cancer sufferer who touched the hearts of people across the country with her unwavering determination to complete a bucket list before her death has passed away.

Katelyn Norman died peacefully at East Tennessee Children's Hospital at 8.19am on Friday. She had been fighting osteosarcoma, an aggressive bone cancer, for two years but doctors told her it had spread to her heart, arteries, pelvis and spine and that there was nothing more they could do.

On learning the prognosis, Katelyn drew up a
bucket list of activities she hoped to complete, including a slow dance, learning to drive a car, spending a day with each of her siblings and visiting Italy.

Loss: Katelyn Norman, a cancer sufferer whose positivity touched people across the country, has died

Just hours after Katelyn passed away in her sleep, a walk at Jacksboro Middle School that was supposed to be a fundraiser to send Katelyn to Italy, instead celebrated her life, reports WBIR.com.

Organizers say the $1,800 raised will go to help her family with expenses. Dozens of girls wore bright green bows in their hair as a symbol of their support for the teen.

Earlier this week her family and friends had ensured she was able to tick off one desire: Attending a prom.

She was supposed to attend the event in her honor in LaFollette, Tennessee on
Tuesday night, but had to be airlifted to
hospital earlier in the day after struggling to breathe.

But it did not stop her. Classmates and
relatives brought the party to her bedside instead, bringing balloons,
music and her smartly-dressed date to make sure she didn't miss out.

Katelyn, who was in a stable condition
and high spirits on Tuesday night, was pictured grinning as her date
bent down to her hospital bed to present her with her corsage.

Outside the hospital, thousands of
people lined along Highway 63 as part of a candle-lit vigil for Katelyn,
who had insisted that a party continue in her absence.

A Facebook page supporting Katelyn
run by her best friend Brandon Huckaby has been flooded with messages of
condolences and love for the family.

Huckaby posted a poem by an unknown
author called 'Four Candles' on the Facebook page shortly after Katelyn
died that ended with, 'We cherish the special place in our hearts that
will always be reserved for you. We thank you for the gift your living
brought to each of us. We love you. We remember you.'

One of the other items on Katelyn's
bucket list was to see the band Of Mice & Men in concert and get an
autographed T-shirt from them.

The band's fans flooded their Facebook
page and Twitter accounts with links to Katelyn's story, urging them to
reach out to her.

The band's lead vocalist Austin Carlile tweeted about Katelyn earlier in the week and again today.

'I told her not to be afraid because
she wouldn't be alone,' Carlile tweeted. 'My mom is already an angel and
would be taking care of her.'

'Heaven gained another angel this
morning. #RIPKatelynNorman Her light will never go out. She'll always be
in my heart. I promised her that,' he wrote.

A fundraising page to help pay for
Katelyn's wish list has produced an outpouring of affection and
generosity towards the teen. The page has raised more than $80,000, most
of which has been donated this week.

Donations will be withdrawn from the
site on April 2. The check will be sent to Katelyn and her family, along
with copies of all of the messages of support.

The website, GoFundMe.com, takes a percentage from each donation, but the rest of the money will be sent to the family.

Some of the money will go to churches
and families that Katelyn wanted to support, she told her mother. The
money will also be used to cover funeral expenses.

'I've never seen this community come
together quite as much as they have over one single person,' said Sharon Shepherd, an instructor at Katelyn's school and prom coordinator.

'[Katelyn] will change your life. You'll never be the same. She
will make an impact on you. She's a jewel. My life will never be the
same.'

A motorcycle riding club helped
Katelyn check off another item by organizing a ride down Campbell
County's main drag, although she was too weak to ride.

'That was amazing just seeing everybody. Rolling down the windows just saying hi to everybody,' said Katelyn after the event.

Originally Katelyn had been due to attend Tuesday night's prom which was held at The
Stables in LaFollette, and had been personalized for the teenager, with the
theme 'Katie in the Sky with Diamonds'.

'She contacted me and said prom must go
on, that's her, and you can't help but feed off that energy, that life,'
Sharon Shepard, an instructor at Katelyn's school and prom coordinator, told WATE-TV.

Friends
danced, ate and drank at the party, and posed in front of Italian
landscape backdrops - a nod to Katelyn's other dream to visit Italy, a dream she never fulfilled.

The Campbell County mayor, William
Bailey, also attended the prom - where he announced Tuesday - March 26 -
would be known as 'Katelyn Norman Day'.

'We
wanted to try to make this day, and this time in her life, special to
her because she makes it special for people in Campbell County,' he
said.

Katelyn's mother, Erica Nelson,
previously said they hoped to complete as many activities as possible as
she spent her last days at home.

'I just want to give her what she isn't
going to see and just try to fulfill what she wants to do. It's not
really much, but it's something to her,' she said.

'We're very grateful that they're wanting to come help Katelyn. She's
touched a lot of people.'

Sharon Shepard, the school nurse at Campbell County High School, where Katelyn attends, told ABC News the teenager is unlike anyone else.

'[Katelyn]
will change your life,' she said. 'You'll never be the same. She will
make an impact on you. She's a jewel. My life will never be the same.

'She's
a fighter. She's just very opinionated and very well-spoken, very
headstrong, very driven and that's what has gotten her this far.'

Her best friend Brandon Huckaby, 16, added to ABC: 'She's always used her sense of humor
and her grab on others to push to make everything better for everyone.

Fighting back: On Tuesday she completed one bucket list item - going to a prom at her school

Family: She said that her siblings, pictured, are struggling to come to terms with her illness

Upbeat: Her friends and family said she stayed positive and confident despite her prognosis

'She doesn't care that she's suffering.
She cares that other people are suffering and she wants to stop that.'

He
said that, although he's sad about losing his friend, he knows he must
help her complete her final wishes. 'This is happening,' he said. 'I'm
getting this done.'

Katelyn was diagnosed with the bone
cancer in her right arm in May 2011, after a friend punched her arm and
it went limp. X-rays revealed abnormal bone and she was found to be
suffering from cancer in her arm and nodules in the lungs.

She underwent bone
transplants, surgeries of tissue ligaments and chemo for her lungs, but
they failed to ward off the illness.
